Before this is the default, could someone tell us what we may be doing wrong here with using NVME as the diskif?

In case it matters, this is changing the default that zadm uses when creating VMs. The zone default, i.e. what you get if you don't set the diskif property in the zone config, will remain virtio.

The instability you're seeing on Windows is very odd. It should be a standards-compliant emulation (it's actually been tested for this in FreeBSD where it originates). Is there any more information in the event log entry that preceded the reset? (I'll reply on the list).
